dt-bindings: display: convert sharp,ls043t1le01 to DT Schema

Browse Source 
The txt binding specified the property "power-supply".
But the example and the actual implementation in the linux-kernel
uses "avdd-supply".
So the binding is adjusted to use avdd-supply as this seems
to be the correct choice.
There are no DT files in the linux kernel to check.

Sharp Microelectronics 4.3" qHD TFT LCD panel
Required properties:
- compatible: should be "sharp,ls043t1le01-qhd"
- reg: DSI virtual channel of the peripheral
- power-supply: phandle of the regulator that provides the supply voltage
Optional properties:
- backlight: phandle of the backlight device attached to the panel
- reset-gpios: a GPIO spec for the reset pin
Example:
mdss_dsi@fd922800 {
panel@0 {
compatible = "sharp,ls043t1le01-qhd";
reg = <0>;
avdd-supply = <&pm8941_l22>;
backlight = <&pm8941_wled>;
reset-gpios = <&pm8941_gpios 19 GPIO_ACTIVE_HIGH>;
};
};
